' HEATING STOVE on FURNACE.

SPECIFICATION forming part of Letters Patent No. 378,019, dated February 14-, 1888.

Application filed April 26, 1886. Serial No. 200,163. (No model.)

To all whom it may concern:

Be it known that I, LLEROY ROWE, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heating Stoves or Furnaces, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates especially to furnaces or stoves having a fire-pot provided with a section having vertical recessesor openings connecting the fire-pot with a chamber in the front of the stove or furnace, connected with the combustion-chamber and downflues of the furnace or stove by means of suitable openlngs or spaces.

It further relates to a hole through which ashes escape from the said chamber to the ashpit, which hole is adapted to be automatically opened upon the movement of the grate in shaking the stove, so that the ashes are auto matically dumped or let fall into the ash-pit.

In the drawings I have represented the invention as applied to a heating-stove.

Figure 1 represents a vertical section of a stove of this character containing the features ofmyinvention. Fig.2 is a view in perspective of the fire-pot wall,vertical flue-plates,and base of the stove, to furtherillustrate the construction ofthe invention. Fig. 3 is a View in horizontal section upon the line so xof Fig. 1. Fig. 4 is a View in detail to illustrate the construction of mechanism for operating the cover to the opening of the ash-pit, hereinafter referred to; and Fig. 5 is a detail view to illustrate the connection between the chamber a to the front of the stove, hereinafterreferred to, and the down takes or flues of the stove.

A is the ash-pit; B, the grate; O, the firepot; c, the casing about it; c, the lining; 0 the coal-guard; D, the combustion-chamber;

cl, the direct escape-port controlled by the damper d. v

. E E are the flues or takes, which are arranged between the casing c and the outer casing, e, of the stove, and which openattheback of the base into the uptake 6. The casing c of the fire-pot and the lining c extend about three-quarters around the fire-pot wall, (although I donot confine myself to the proportion.) Theother part of section is made up or composed of the section F, which prefer; ably is a casting having the lower bar, f, the upper bar, f, and the vertical bars f separated from each other to provide vertical spaces f 'Theserecesses or spaces connect the fire-pot with the chamber G, and this chamber is formed by means of the plates 9 g, which extend from each edge of the casing c, or from each edge of the firebrick, to the outer casing of the stove. The lower wall of this chamber is formed by the section 9 of the upper base-plate, and the upper wall by the coal-guardrf, which may or may not be provided with apertures. This chamber is connected with the combustion-chamber and with the down fines or takes E E by means of the openings g above the plates'g g, formed by not extending the plates g g to the coal-guard 0 1 There is an opening, 9, through the front casing of the furnace to this chamber G,which is closed by a door, 9 which may carry mica or other lights.

The section 9 of the base-plate has an opening, h, which is closed by a cover or plate, H. This opening connects the chamber G with the ash-pit, and as it is desirable that the air for supporting combustion should pass from the ash-pit through the grate and'not through this opening, it is necessary that the cover or plate H be moved to expose or open the aperture or openingonly when the grate is-shaken,

or when it is desired to remove or dump ashes which have fallen thereon or into the lower part of the chamber G. To accomplish this v purpose I have hinged the plate or cover H at its outer edge, h, to the section 9 of the baseplate, and so as to swing downwardly into the ash-pit; and I have secured or attached to the slide h for oscillating the grate B, and also for moving a section thereof outwardly to dump it, arod, h, having an upwardly-bent outer end,-h and carrying at its inner end an,

arm or projection, h, which acts as'a support for the cover or plate H. The rod 71. is movable upon the slide If, and is movable with the slide h The outward movement of the slide it, however, does not withdraw the support or arm h from beneath the cover or plate -H,' so i that the grate can be moved in dumping the contents of the fire-pot without moving the cover or plate H; but when the slide is oscillated to shake the grate the arm or support h turns with the rod and falls and the cover or plate H swings downward automatically. To close the opening, it is necessary to turn the rod to bring the arm or support It into a vertical position beneath the plate.

Of course the support or arm It may be turned to permit the falling of the cover or plate at any other time by simply turning the rod h,- and I would state that I do not confine myself to the especial construction herein described for connecting the grate or grateoperating slide, bar, or rod with the cover or plate H, but may use any mechanical equivalent for the device herein described for automatically releasing or causing the opening of the cover or plate upon oscillating said grate bar or slide.

In usea portion of the products of combustion and heat pass from the fire-pot into this chamber, and from thence directly to the downflues, or through the combustion-chamber to the downfiues; and by providing the chamber with a door access is bad at all times to the side of the fire and to the fire-pot exposed by the openings or'spacesf Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination, in aheating stove or furnace, of the continuous fire-pot casing or shell 0, the outer casing, e, and the vertical partition-plates g g, forming the downflues E E, the combustion-chamber D, the section 9 of theupperbase-plate, forming,with the partition-platesgg', the chamber G, which is closed at its bottom and sides and which opens into the downflues E E, and the section F of the fire-pot wall, having the openings f extending from the fire-pot into the chamber G, as and for the purposes described.

2. In a heating stove or furnace, in combination with the fire-pot O and the combustionchamber D, the chamber G, formed by the plates g,g, and g and opening into the downfiues E E, the section F of the fire-pot wall, having the openingsf connecting thefire-pot with the said chamber G, the casing 6, having an opening, 9, to the said chamber G, and the doorg for closing said opening, substantially as described.

3. The combination of the chamber G, the base-plate y the opening h in the base-plate from the chamber G, the cover or plate H, hinged to the base-plate to swing downwardly into the ash-pit, and the closing arm or device h, substantially as described.

4. The combination, in aheating stove or furnace, of the chamber G, having an opening, h, to the ash-pit chamber, which is normally closed by a hinged cover or plate, H, the said cover or plate H, the grate slide or bar h and a device connecting the slide or bar with the cover or plate H, adapted to be operated by the movement of the slide or bar it in oscillating the grate to automatically release the cover H to expose or uncover the opening h, substantially as described.
